| Definition | Marine seismic sources that send sound pulses into the sub-sea floor sediments. The sound pulses bounce off the sea floor and subsequent buried sediment layers according to differences in their acoustic impedance (hardness) and in turn, their density. Pingers are linear, single channel, high frequency systems that typically operate at frequencies greater than 2 kHz and penetrate to several tens of metres. | ||
